Patent FR-2379795-A1 (FR)
Title: Land mine detonating system - uses short microwave impulses with measurement of reflected wave transit time
IPC: F42C13/04
Filed: 1969-10-15
Abstract: The land-mine detonator is particularly for an anti-tank mine, and is connected to an emitter and receiver of short micro-wave impulses. It is fired by the emitted impulses reflected by an object on the mine. The transit time of the reflected micro-wave impulse can be used to determine the distance of the object, and the detonator can be so arranged as only to be fired when the reflected impulses emanate from a particular zone at a distance away. Systems can be included to determine the difference between the amplitudes of reflected impulses from objects of different kinds, these amplitudes deciding whether or not the detonator is fired.

Title: Blow moulding with neck of blank held by segmental mould
IPC: B29C49/48
Filed: 1973-12-04
Abstract: An injection and blowmoulding machine for making hollow plastics objects such as flasks or bottles, comprises one or more cores which alternate between an injection station where a rough is injected and a finishing or blowmoulding station comprising an opening blowmould and also an opening mould for the neck of the bottle. The segments constituting this neck mould are mounted on the base block for the core, surrounding the base portion of the core itself and are driven by their actuating rams along a diverging-converging direction generally longitudinally of the core; the fluid lines for inflating and heating fluid are constituted of ducts formed in the complex of the core unit. Pref. a number of cores are mounted by means of intermediate plates on a common support by which they are moved between the injecting and blowmoulding stations. The cores are on opposite sides of the support which can revolve about an axis, so that one of the cores co-operates with the injection unit while the other is co-operting with the blowmoulding unit. With this arrangement, the neck mould segments are opened to release the blowmoulding when completed at the same time as the core is withdrawn. The arrangement results in a reduction of total cycle time.
